JOHN BRUNEAU, OF GLIOHY, PARIS, FRANCE.

VAPOR-BURNER.

Specification of Letters Patent.

Patented Dec. 24, 1907.

Application filed May 26.1906- Serial No. 318,972.

To all whom it may concern:

Be it known that I, JOHN BRUNEAU, a citiflame flickers owing to a draft or some other 1 cause, the vaporization as a result being irregular and imperfect.

The present invention having for its object to overcome this inconvenience consists in arranging within the annular vaporizer a superheating chamber which becomesv ex posed to an intense heat since the annular vaporizer draws the heat up through the inner space containing the superheater. Should the flame by a draft or other influence be caused to flicker, this will exert no detrimental influence on the superheater, the latter holding sufiicient heat to keep the fuel vaporized.

The invention is illustrated in the accompanying drawing where device here referred to in vertical section. Fig. 2 is a modification.

1 is the annular vaporizer which is connected with the supply-pipe 2 for the fuel and with a superheater 5 arranged within the vaporizer and communicating with the discharge-nozzle 4 by means of a pipe 3. To prevent fuel which is not comp etely vaporized from entering the superheater, the connecting pipe 6 between the latter and the va orizer 1 preferably extends to the upper en of the vaporizer. As a result of this arrangement the vaporizer must be comletely filled with fuel before the latter can ow into the superheater which will conse- Figure 1 shows the quently contain completely vaporized fuel only. The pipe 3 may moreover extend to the upper end of the superheater 5 In the form shown in Fig. 2 the superheater 5 is itself formed into a connecting pipe 6 communicating with the vaporizer 1 and then passing directly into the pipe 3 leading to the burner. This construction is much more simple than the former though not so eflicient. It may be evident that the invention is not limited to the forms illustrated which may be varied in many ways without departing from the principle of the invention, the main feature of which consists in the arrangement within the annular vaporizer of a superheater, communicating with the said vaporizer and the discharge nozzle.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

In a vapor burner a closed vessel of annular cross-section connected with the oil supply and arranged centrally above the burner, a second closed vessel of cylindrical crosssection of smaller diameter than the inner space of the annular vessel centrally inserted in the latter, a pipe of communication starting from the bottom of said cylindrical vessel and reaching up into the annular space to near the top of the annular vessel, a feed pipe leading to the burner from a point near the top of the cylindrical vessel, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN BRUNEAU.
